Planning a trip to San Juan, Puerto Rico; which airline is the cheapest to get there?

Hello, suppose you fly from new york on the dates i randomly picked, the flight details below are for your reference:

New York (JFK) to San Juan (SJU) - Tue, May 1

Delta 301 Dep: 8:30AM Arr: 12:33PM 4h 3m Boeing 757 Economy (U)

San Juan (SJU) to New York (JFK) - Tue, May 8

Delta 326 Dep: 8:15AM Arr: 12:24PM 4h 9m Boeing 737 Economy (U)

The total cost per passenger (including taxes & fees) is $279.40.

The cheapest airline to Puerto Rico is, always has been and probably will always be SPIRIT AIRLINES and you have to book your flight through their web site to get the best prices. It's a no frills airline and you do NOT want to take any luggage because they even charge you for putting your bags in the overhead compartments. You need to take just one SMALL suitcase that will fit under the seat in front of you or it will cost you a fortune for BAGGAGE.

If you are so simple minded and IMMATURE that you have to be constantly entertained and have your weak mind constantly stimulated.. then buy a romance magazine an read it on the 2 hour trip.

Since you were able to find this group, is there some reason you can't go to GOOGLE and type in PUERTO RICO TORUIST INFORMATION and hit ENTER?
